Genes affected

MYB (HGNC:7545): (MYB proto-oncogene, transcription factor) This gene encodes a protein with three HTH DNA-binding domains that functions as a transcription regulator. This protein plays an essential role in the regulation of hematopoiesis. This gene may be aberrently expressed or rearranged or undergo translocation in leukemias and lymphomas, and is considered to be an oncogene. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2016]

The c.1365G>A (p.M455I) alteration is located in exon 10 (coding exon 10) of the MYB gene. This alteration results from a G to A substitution at nucleotide position 1365, causing the methionine (M) at amino acid position 455 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
